Description

Terminal device, base station device, and communication method

Technical Field

The invention relates to a terminal device, a base station device and a communication method.

Background

In the third generation partnership project (3GPP), a radio access method and a radio network (hereinafter referred to as long term evolution or evolved universal terrestrial radio access) for cellular mobile communication have been studied. In LTE (long term evolution), the base station equipment is also referred to as evolved node b (enodeb) and the terminal equipment is also referred to as User Equipment (UE). LTE is a cellular communication system in which a plurality of areas are deployed in a cellular structure, wherein each of the plurality of areas is covered by a base station apparatus. A single base station apparatus may manage a plurality of cells. Evolved universal terrestrial radio access is also known as E-UTRA.

In 3GPP, next generation standards (new radio: NR) have been studied to propose international mobile communications 2020(IMT-2020), which is a standard of next generation mobile communication systems defined by the International Telecommunications Union (ITU). NR has been expected to meet requirements considering three scenarios, enhanced mobile broadband (eMBB), large-scale machine type communication (mtc), and ultra-reliable and low-latency communication (URLLC) in a single technology framework.

For example, a wireless communication device may communicate with one or more devices using a communication structure. However, the communication structure used may provide only limited flexibility and/or efficiency. As the present discussion illustrates, systems and methods that improve communication flexibility and/or efficiency may be advantageous.

Here, N_initAre values randomly (or pseudo-randomly) selected from integer values in the range of 0 to CWp. CWp is the Contention Window Size (CWS) for the channel access priority p.

Step A2 includes operations that proceed to step A3 when the counter N is not zero. In fig. 12, "true" corresponds to the fact that the evaluation formula is true in the step including the operation of determining the evaluation formula. In addition, "false" corresponds to the fact that the evaluation formula is false in the step including the operation of determining the evaluation formula. In step a2, the evaluation formula corresponds to a counter N of 0.

For example, step A3 may include the step of decrementing the value N of the counter. Decrementing the counter value N may be the decrementing of the counter value N by one. That is, decrementing the value of the counter, N, may be setting the value of the counter, N, to N-1.

Further, step a4 may include proceeding to step a2 when it is determined by carrier sensing that the LBT slot duration d is idle. Further, step a4 may include an operation of performing carrier sensing in the LBT slot duration d, and an operation of proceeding to step a5 when the LBT slot duration d is busy. Further, step a4 may include proceeding to step a5 when it is determined through carrier sensing that the LBT slot duration d is busy. Here, the LBT slot duration d may be the next LBT slot duration of the LBT slot duration that has been carrier sensed in the counting process. In step a4, the evaluation formula may correspond to the LBT slot duration, d, idle.

In step a5, the medium is idle until it is detected that the medium is busy for a particular LBT slot duration included in the delay duration; or the medium is idle for all LBT slot durations included in the delay duration. This includes operations to perform carrier sensing until "idle" is detected.

Step a6 includes proceeding to step a5 when the medium is detected to be busy for a particular LBT slot duration included in the delay duration. Step a6 includes operations that proceed to step a2 when medium idle is detected for all LBT slot durations included in the delay duration. In step a6, the evaluation formula may correspond to the medium being idle for a particular LBT slot duration.

For PUSCH scheduled by a DCI format with CRC scrambled by TC-RNTI, frequency domain resource allocation information is provided by a frequency domain resource allocation field in the DCI format. The resource block allocation information in the frequency domain resource allocation information indicates a set of VRBs for the PUSCH. For a DCI format with CRC scrambled by TC-RNTI, the frequency domain resource allocation information may not include resource allocation type information.

For the PUSCH that is scheduled by the random access response grant, the frequency domain resource allocation information is provided by the random access response grant. The resource block allocation information in the frequency domain resource allocation field indicates a set of VRBs for the PUSCH. Here, if N is^size _BWPEqual to or less than 180, the frequency-domain resource allocation field is truncated to ceil (log2 (N) of the frequency-domain resource allocation field^size _BWP*(N^size _BWP+1)/2)) LSBs (least significant bit). Here, N^size _BWPIs the number of resource blocks in the initial UL BWP for terminal device 1 in the case of PUSCH scheduled by the random access response grant. In addition, if N is^size _BWPGreater than 180, the value is set to floor (log2 (N) of' 0^size _BWP*(N^size _BWP+ l)/2)) -14 MSBs (most significant bit) at N_ULhopThe bits are then appended to the frequency domain resource allocation field. Here, N_UL,hopIs the number of bits of the frequency offset value indicating the frequency hopping. N is a radical of_UL,hopCan be 0,1 or 2, based at least on the value of the hop flag field in the random access response grant and N^size _BWPThe value of (c). The truncated frequency domain resource allocation field or the additional frequency domain resource allocation field provides frequency domain resource allocation information.

The truncated frequency domain resource allocation field or the additional frequency domain resource allocation field may be interpreted as a frequency domain resource allocation field used in the DCI format 0_0 detected in the CSS set.

The truncated frequency domain resource allocation field or the additional frequency domain resource allocation field may be interpreted as a frequency domain resource allocation field used in the DCI format 0_0 detected in the CSS set in the same manner.

The truncated frequency domain resource allocation field or the additional frequency domain resource allocation field may be interpreted based on an assumption that DCI format 0_0 is detected in the CSS set.

There are at least 3 interpretations of the frequency domain resource allocation field. The first explanation is for the case where DCI format 0_0 is detected in the CSS set. The second explanation is for the case where DCI format 0_0 is detected in the USS set, and the number of bits of the frequency domain resource allocation field in DCI format 0_0 (or the number of bits of DCI format 0_ 0) is derived from the size of the active UL BWP for terminal device 1. The third explanation is for the case where DCI format 0_0 is detected in the USS set, the number of bits of the frequency domain resource allocation field in DCI format 0_0 (or the number of bits of DCI format 0_ 0) is derived from the size of the initial UL BWP for terminal device 1, and the frequency domain resource allocation field is applied to an active UL BWP different from the initial UL BWP.

The resource block allocation information in the frequency domain resource allocation field indicates a set of VRBs for the PUSCH. The frequency domain resource allocation information may include N_UL,hopBit hopping offset information and resource block allocation information. VRBs are in active UL BWP for terminal device 1.

Hereinafter, a first explanation is described for a case where DCI format 0_0 is detected in a CSS set.

In fig. 13, each block represents a resource block. In fig. 13A, each block represents a VRB. In fig. 13B, each block represents a PRB.

The resource allocation of the PUSCH in the VRB domain is indicated by RIV (resource indication value), which is determined by resource block allocation information. RIV indicates index RB of PUSCH_startStarting VRB and length L of VRB to allocate continuously_RBsIn terms of length.

In case the resource block allocation information indicates RIV, the resource block allocation information is also referred to as type 1 resource allocation field.

In (L)_RBs-1) less than or equal to floor (N)^size _BWPIn the case of/2), RIV equals N^size _BWP*(L_RBs-1)+RB_start. In (L)_RBs-1) greater than floor (N)^size _BWPIn the case of/2), RIV equals N^size _BWP*(N^size _BWP-L_RBs+1)+N^size _BWP-1-RB_start. For the first explanation, N^size _BWPIs the number of resource blocks for the initial UL BWP of the terminal device 1. For the second explanation, N^size _BWPIs the number of resource blocks for active UL BWP for terminal device 1.

For the third interpretation, the formula for deriving the RIV is different from the first interpretation and the second interpretation.

In fig. 13A, VRBs allocated to PUSCH are indicated by upper left oblique lines. The VRB allocated to the PUSCH is mapped to the corresponding PRB through VRB-to-PRB mapping. In VRB-to-PRB mapping, a VRB with index N is mapped to a VRB with index N + N, if condition X is satisfied^start _BWP,0-N^start _BWP,iThe PRB of (1). In addition, in case the condition X is not satisfied, a VRB having an index n is mapped to a PRB having an index n. The condition X includes part or all of the condition X1, the condition X2, the condition X3, the condition X4, the condition X5, and the condition X6. Conditional X1 is that PUSCH is scheduled by a random access response grant. Conditional X2 is that PUSCH is scheduled by DCI format with CRC scrambled by TC-RNTI. Conditional X3 is that the PUSCH is in active UL BWP with index i for terminal device 1, where N is^start _BWP,iIs the index of the starting common resource block of the active UL BWP with index i. Condition X4 is that the active UL BWP with index i includes all physical resource blocks of the initial UL BWP for terminal device 1, where N is^start _BWP,0Is the index of the starting common resource block of the initial UL BWP. Condition X5 is that the active UL BWP with index i is configured to have the same subcarrier spacing as that of the initial UL BWP. Condition X6 is that the active UL BWP with index i is configured to have the same CP length as the CP length of the initial UL BWP.

For example, condition X may be that PUSCH is scheduled by a random access response grant or a DCI format with CRC scrambled by TC-RNTI in an active UL BWP, the active UL BWP including all physical resource blocks of the initial UL BWP, the active UL BWP having the same subcarrier spacing as the initial UL BWP, and the active UL BWP having the same CP length as the initial UL BWP.

In fig. 13B, in the case where the condition X is satisfied, PRBs allocated to the PUSCH are indicated by upper left slashes based on the VRB-to-PRB mapping.

For NR-U (unlicensed new radio), the frequency domain resource allocation procedure for PUSCH can be enhanced by using an interlace-based approach to meet the requirements required for NR-U. The interlace-based approach may be that the resource block allocation information indicates a set of interlaces that each include one or more resource blocks. Here, each of the interlaces may include one or more CRBs, one or more PRBs, or one or more VRBs.

For example, the indication method may be based at least on RIV. Here, in the indicating method, the resource block allocation information indicates a start index of an interlace used for the PUSCH and the number of interlaces allocated to the PUSCH.

For example, the indication method may be based at least on a bitmap. Here, in the indication method, the resource block allocation information includes a bitmap, wherein each bit in the bitmap corresponds to an interlace.

Fig. 14 is an example of interleaving in a frequency domain resource allocation process in accordance with aspects of an embodiment of the present disclosure. In fig. 14, each block represents a resource block. In addition, horizontal lines indicate interleaving 2001. In addition, the upper left slash indicates the staggering 2002. In addition, diagonal grid lines indicate the intersections 2003. In addition, the grid lines represent the interlaces 2004. In addition, the upper right slash indicates the interlace 2005. Total number of interlaces N in BWP (or SCS-specific carrier)_MMay be 5, 10 or other.

As shown in fig. 14, each resource block in the aggregated bandwidth 2013 may be included in an interlace. The staggered index may be cyclically allocated to each resource block in the frequency domain. Here, point 3000 is a reference point of interlace index allocation. For example, as in fig. 14, an index of 0 may be allocated to a resource block including subcarriers having the same center frequency as that of point 3000. For example, with index I_CRBOf a common resource block, I_LCan be based at least on the relation I_L＝mod(I_CRB,N_M) To give. Here, N_MIs the number of interlaces in BWP (or in SCS-specific carriers). For example, with index I in BWP with index I_VRBOf virtual resource blocks I_LCan be based at least on the relation I_L＝mod(I_VRB+N^start,u _BWP,i,N_M) To give. Here, N^start,u _BWP,iIndicating a reference point of the BWP with index i. For example, with index I_LMay comprise a set of virtual resource blocks. With index I_VRBEach of the virtual resource blocks of (a) satisfies I_L＝mod(I_VRB+N^start,u _BWP,i,N_M)。

In fig. 14, there is a gap 2099 between bandwidth 2011 and bandwidth 2012. The gap may be used for potential guardbands for bandwidth 2011 and bandwidth 2012. It is also possible that there is no gap between bandwidth 2011 and bandwidth 2012.

Bandwidth 2011, bandwidth 2012, and gap 2099 can be aggregated into aggregated bandwidth 2013.

In this case, the VRB allocated to the PUSCH may be represented by upper left slash and slash grid lines. All other outlined boxes are not allocated to PUSCH.

For a PUSCH scheduled by a random access response grant or a DCI format with CRC scrambled by TC-RNTI, careful processing of resource block allocation for the PUSCH is required because the base station apparatus 3 cannot identify the terminal apparatus for which the base station apparatus 3 needs to grant the PUSCH.
